Wireless Messaging between two Ti-84 Calculators

I'm currently working on a project where I make two calc ti84+ wirelessly message each other using a 2x Arduino Uno and a 2x nrf24l01 module. i connected the calc to my arduino using a 2.5mm jack. i used the Articl library, and it seems to work for sending characters from Arduino to a calc. i have no idea how to receive it from the calc. my idea is to get the sending and recieving from the serial monitor and calc achieved. if that is working, then i replicate this on another TI84+ calc and then ...

TI calculator tribute video (84+CE games)

It has been a while since I posted anything calculator-related on my Youtube channel, so I decided to make a tribute video about TI-84 Plus CE and TI-83 Premium CE games and it's now available on Youtube. It misses some games I wanted to include because the animated screenshots were in a weird APNG or whatever format that is not compatible with most free video editor, but it includes over 9 minutes of gameplay: games can be downloaded on https://tip...

WARNING: Do NOT upgrade your TI-84 Plus CE to OS 5.5 and higher. It blocks ASM!

I saw this coming years ago as critor would say, but it is now a reality: Texas Instruments has decided to block ASM on the TI-83 Premium CE and TI-84 Plus CE.Looks like from now on ASM will have to be added via hacking or whatever, like on the Nspire. Hopefully it's not as difficult as with Ndless and hopefully there is a way to get the old games to run on the new OS. But this is bad news for TI development, especially considering most games are coming out on the CE.Source: ...

I mean, think about it! Both the SMS and 84+ CE have similar CPUs, and if the 84 is powerful enough to emulate the GB, it really shouldn't be much of a problem. I honestly would LOVE to just be able to play STH and Alex Kidd on my calc, even if it's the inferior verisons.

Dead project history preservation (gameplay footage)

In the past, many programming projects died due to various factors and more often than not, none of their history was preserved (no source code, no demo, no screenshot left, etc). Because it's impossible to just ask people to take over someone else's project without requiring them to get used to a different style of programming (which often fails), I thought about a different idea that would not necessarily bring back those projects to life, but at least show their past existence.
